There's a way to replace values in grafana?

I have a check mk data source, i have the idea to transform every 0 values into a boolean automatically but i can’t find any way to do this in the transformations i only found solutions for the most used data sources but i ain’t using none of them

Yes you can replace values in grafana please explore the grafana document
Value Mapping

Add field from calculation Transformation

Replace Values Using Overrides

Thanks for the docs, they’ll be very helpful.
Also thanks for your help, but it’s not exactly what I’m looking for. I know about value mappings because I’ve used them a lot, but what I can’t figure out is how to modify the data with a conditional statement that automatically transforms the value 0 to false every time it’s identified, and if it changes to 1, it’s treated as a number.
The intention is that every time a number is received, the KPI displays a box, and every time it’s 0, it’s identified as false and the box disappears.
I hope I’ve explained myself clearly, as it’s a somewhat complex idea to implement.
